The United Kingdom government has expressed continued confidence in Martin Rolfe, chief executive of air traffic control provider Nats, following extensive travel disruptions caused by a system fault on Tuesday. The incident affected tens of thousands of passengers, leading to cancellations and delays at major airports including Heathrow, Gatwick, Manchester, and Stansted. The disruption persisted into Wednesday as airlines and airports worked to manage the ongoing impact.

Transport Secretary Heidi Alexander met with Rolfe on Wednesday morning to address the situation. According to a spokesperson from the prime minister’s office, Alexander conveyed "significant concerns" from both the aviation industry and the travelling public regarding the scale of the disruption. She has instructed Rolfe to conduct a full investigation into the cause of the fault to ensure that the underlying issues are thoroughly understood and that similar incidents can be prevented in the future.

Despite pressure from some airlines, including calls from Ryanair for Rolfe’s resignation, government officials affirmed their support for the Nats chief. When asked whether the confidence in Rolfe was dependent on the results of the forthcoming inquiry, the prime minister’s spokesman emphasized that the government currently stands behind him and expects the investigation to be completed within a week.

The fault occurred amidst a period of heightened travel demand, and airlines such as Wizz Air voiced criticism over the handling of the incident. Nats, responsible for managing the UK’s air traffic control, acknowledged the disruption and committed to cooperating fully with the investigation.

The coming days will likely see continued challenges at affected airports as air traffic control services and airlines work to restore normal operations and accommodate passengers impacted by the backlog. The outcome of the investigation is anticipated to shed light on the technical failure and guide steps to bolster the resilience of the country’s air traffic management systems.
